    Use the Feynman technique:
    1. Write down the problem.
    2. Think really hard.
    3. Write down the solution.

    For #5, there's an obvious substitution to try.

    For the remaining two, look in your notes and book for techniques to try and take a stab at them. You have to show a reasonable attempt before you can get help here.

    You can check it yourself. Take the derivative of your answer. If it's correct, you should end up with the integrand. This is something you should make a habit of doing.
